The purpose of storm water management is to diminish threats to public health and safety caused by floodwaters; reduce economic losses to individuals and the community at large; enhance broader social and economic objectives; protect, conserve, and promote the orderly development of land and water resources; prevent victimizations and fraud; and to comply with the guidelines for the National Flood Insurance Program as published by the Federal Emergency Management Agency (FEMA)

All new construction projects whether for a single family home, an entire subdivision or industrial park, or shopping center must incorporate storm water management practices.  Soil erosion and sediment control measures, storm water conveyance and detention, and special management areas, and best management practices are reviewed for compliance with the Village and Countywide storm water management ordinances.  These two ordinances together are one of the most stringent storm water and flood plain management codes in the nation.

Refer to the DuPage County Countywide Stormwater and Flood Plain Ordinance and the Village of Addison Storm Water and Floodplain Management Ordinance for specific storm water and flood plain management requirements when preparing an engineering site development plan for a proposed project within the Village.

Flood Plain and Floodway

Flood plain is land that is adjacent to and including a body of water where ground surface elevations are at or below a specified flood elevation, and the floodway is the channel and that portion of the flood plain adjacent to a stream or water course that is needed to convey the base flood.  Both the flood plain and flood way are special management areas which require special permitting.

Development requirements for projects within the flood plain can be found in the DuPage County Countywide Stormwater and Flood Plain Ordinance and the Village of Addison Storm Water and Floodplain Management Ordinance.  For additional information, checkout the flood links on the External Links page above.

Water Quality and Best Management Practices (BMP's)

Improving the quality of water discharged into our ponds, streams, and creeks within the Village has taken on greater importance because of the Federal Clean Water Act's National Pollutant Discharge System Phase II (NPDES PII) implementation.  Because of this Federal mandate, the Village and the County are in the process of implementing water quality enhancing measures and expect that those measures will be required early 2008.

Download our Guide to Protecting our Water Quality brochure for some general information.

The Village has been implementing BMP's for some time now.  Village implemented BMP's include requiring construction entrances and silt filter fence around construction sites, installation of french drains and drywells, and providing education and technical expertise to contractors and homeowners.
